The term omega-3 reveals that the first double bond exists as the third carbon-carbon bond from the terminal methyl end of the carbon chain. The chemical structure of alpha-linolenic acid (18:3?9C, 12C, 15C, ALA) given in Fig-1, is an essential n-3fatty acid (18:3?9C, 12C, 15C indicating the chain of 18 carbons with 3 double bonds at 19th, 12th, and 15th carbon).There is a dispute between the chemists and physiologists for naming of the fatty acids as the former ones count them from the co-end of…
